Square made a couple of big move announcements this week. First, the company literally will move to a new office space in the Central Market area of San Francisco by mid-2013, according to a report by Leena Rao at TechCrunch. Rao notes that the company has grown to more than 400 employees and reports Square plans to expand its staff to almost 1,000 people before the end of 2013.

Square also announced this week that its service is now available in Canada, at the same 2.75% rate it charges in the U.S., according to a report by Ingrid Lunden at TechCrunch. Lunden reports one of the obstacles for Square in Canadian as well as European markets is that its dongle depends on the magnetic stripe on the backs of credit cards; many credit card processes in these markets use a chip-and-pin system instead.

The obstacle isn’t insurmountable, however, as Lunden notes, Square’s partnership with Starbucks to incorporate its Pay With Square app service as a mode of payment might pave the way forward with retailers in other markets, making the card processing format irrelevant.

Square competitor PayPal Here was on the move this week as well — into retail shopping. Rao reports in a separate post at TechCrunch that PayPal CEO John Donahoe announced a U.S. retail deal with AT&T during eBay’s earning call this week. PayPal Here previously had a retail presence only in Japan with Softbank. Rao reports that Here will retail for $15, with the purchaser receiving a $15 discount upon signing up; Square is sold in 20,000 outlets in the U.S. and sells for $10, with a $10 purchaser sign-up discount, Rao reports.

Let the mobile payment testing begin

The long-awaited Isis mobile wallet began testing this week in Austin and Salt Lake City markets. Stephanie Mlot reports at PC Magazine that compatible phones at launch include Samsung Galaxy S III, Galaxy S Relay 4G, and Galaxy S II on T-Mobile; the HTC Droid Incredible 4G LTE on Verizon, with Motorola Droid Razr HD and Droid Razr Maxx HD support coming yet this week; and the Samsung Galaxy S III, the HTC One X, the Samsung Exhilarate, the LG Escape, and the Samsung Galaxy Rugby Pro on AT&T.

Mlot also reports that T-Mobile customers can get $10 in Isis eCash if they visit a brick-and-mortar location and activate the application. At launch, Isis works with Chase, Capitol One, Barclaycard, American Express, Visa, Mastercard and Discover credit cards.

As to Isis’ success, a report at Consumer Reports says services like Isis are solving “a non-existent problem” and concludes: “Isis, like Google Wallet, still seems to require a lot of work and needless complexity for the questionable convenience of paying by cell phone.”

Apple also announced this week that it too soon would be testing a mobile payment solution in a limited market — its own retail stores. Mark Gurman reports at 9to5Mac that Apple is preparing to update its point of sale system to scan Apple Store payment card codes through Passbook. The payment system update could be ready as early as the end of this month. Jordan Golson writes at MacRumors that though it’s not confirmed, it’s possible in-store customers also will be able to pay for any merchandise using their iTunes account information; thus far, only select accessories have been available for purchase through Apple’s EasyPay self-checkout system.

Google Wallet on the iPhone?

Business Insider’s Owen Thomas was paying close attention this week, noting the “The next version of Google Wallet, coming soon” statement at the top of Google’s Wallet homepage, with an option for visitors to request an invite. Thomas reports that when he requested the invite, he was prompted to select the type of device he uses: iPhone, Android, or “other.”

Ryan Kim at GigaOm agrees with Thomas’ assertion that this likely suggests Google is looking to expand its purview beyond Android phones and into iPhones and “others,” but notes it really could mean anything. Kim writes:

“It could mean that Google may be pursuing a more cloud-based approach to payments that doesn’t require NFC for transactions. Or Google Wallet could integrate with Apple’s Passbook or evolve to support QR codes or 2D barcodes, which is how Starbucks and Dunkin Donuts handle mobile payments. Or it could just mean Google wants to know how many iPhone users are interested in Google Wallet.”
